Slide the roll grooving unit onto the guide arms (8) until the drive shaft of the
roll grooving unit is projecting with its 3 faces into the quick-action hammer
chuck. Close the latter until the clamping jaws are in contact with the 3 faces
of the drive shaft. With the clamping ring (9), tighten the drive shaft after a
brief opening movement with one or two hard turns. Position and bolt the
hydraulic hand pump (10).
2.3. ROLLER'S roll grooving attachment on ROLLER'S Robot 2 and 4
Refer to instructions for use of ROLLER'S Robot. Swing in the pipe cutter
and the inner pipe deburrer. Undo the wing screw on the clamping ring.
Remove the tool set. Take out the cuttings tray. Place the hose end deta-
ched from the tool holder inside the coolant tray to ensure that oil can cir-
culate. In the case of machines supplied from November 1999 onwards, a
hole is provided in the coolant tray into which the hose end can be inserted.
If required, this hole can be drilled with a 14 mm bit. Lubricant must circu-
late inside the pump to prevent it being damaged. Ensure without fail that
the machine is horizontal when on a mobile stand (by removing wheels or
placing the two stand pipes underneath).

brief opening movement with one or two hard turns. Position and bolt the

2.4. Material support
Caution! Even when in short lengths, pipes must be supported using the
height-adjustable ROLLER'S Assistent or other suitable material supports
depending on their diameter (and weight!), in order to ensure that the machine
does not tip forward.
3. Operation
3.1. Tools
Three sets of grooving rollers are needed for the full working range. Each
set of grooving rollers comprises the upper pressure roller (11) and the low
counterpressure roller (13).
Changing the grooving rollers
Operate the drive machine in inching mode using the pedal switch (4) until
the securing bolt of the counterpressure roller (13) is pointing downwards.
Undo the securing bolt and pull out the counterpressure roller (13). Turn the
pressure roller (11) until the mark on the stub shaft (12) is pointing down-
wards. Undo the securing bolt and slowly pull out the stub shaft (12). Remove
the pressure roller from underneath.
Caution! Before pulling out the stub shaft (12), place your hand underneath
the pressure roller (11) – otherwise it will fall onto the floor!
Insert the selected pressure roller from underneath and slide in the stub shaft
(12). The mark on the latter must be pointing downwards. Tighten the secu-
ring bolt of the pressure roller in the direction of the shaft mark. Insert the sel-
ected counterpressure roller. Note the position of the drive dog (flat edge) on
the rear end of the counterpressure roller. Tighten the securing bolt.
3.2. Working procedure
Pipe ends must be cut off at right angles. Welds or welding residues (beads)
in the pipe must be sanded off over a length of some 50 mm from the pipe
end. Clean any dirt and scale off the inside and outside of the pipe ends.
Close the pressure limiting valve (16). Place the pipe on the counterpres-
sure roller and press it against the machine. Align the pipe axis-parallel, sup-
porting it as necessary. Operate the feed lever (15) of the hydraulic hand
pump several times and feed the pressure roller (11) forward until it is up
against the pipe. Set the stop for the groove depth (17); to do so, turn the
setting disc for groove depth (18) to a stage corresponding to the pipe size
between the housing and the stop plate, and move the stop inwards until it
is up against the setting disc. Secure the stop plate using a locking nut. Turn
the setting disc back to the engagement position so that the stop plate can
be moved downwards. Operate the machine at top speed. Switch on the
machine using the pedal switch (4), operate the feed lever (15) several times,
and slowly slide the pressure roller (11) into the pipe while the machine is
running until the stop plate is touching the housing (pressure on feed lever
increases). Keep the machine running a few more turns without feed. Then
shut down the machine, open the pressure limiting valve (16), remove the
pipe, and check the groove made. To do so, use the diameter measuring
tape or the slide rule at a 90° angle. If necessary, adjust the stop (17) and
repeat the procedure. 1 scale graduation on the stop plate corresponds to
an infeed of approx. 0.4 mm, a complete revolution is 1.5 mm.
3.3. Support of the material
Pipes and long pipe sections must be supported. Ensure here that the support
keeps the pipe at right angles and parallel to the roll grooving machine axis.
4. Maintenance
Pull out the mains plug before starting any maintenance and repair work! This
work may only be performed by experts and trained personnel.
4.1. Servicing
Lubricate the roll grooving unit at the lubricating nipple (19) every 40 wor-
king hours. Use ROLLER'S transmission grease, article no. 091012.
4.2. Inspection/maintenance
See also the instructions for use of the respective drive machine ROLLER'S
Robot.
Check the hydraulic oil level regularly. To do so, unscrew the hydraulic hand
pump and hold it with its rear end vertically upward. Open the pressure
limiting valve (16), unscrew the oil dipstick (20) in the lid of the container,
and check the oil level. If necessary, top up with ROLLER'S hydraulic oil, ar-
ticle no. 091026. Always heed the marks on the oil dipstick – do not pour in
too much oil.
Change the hydraulic oil completely at last every 12 months. To do so, tilt
the container to drain off the old oil, which must be disposed of without har-
ming the environment.
